A Water Bubble (also called a Water Ball) is a giant bubble found in New Super Mario Bros. Wii. They appear in World 7-2 and can be swam in. Mario can use the Water Bubbles to swim to higher platforms. Bullet Bills that fly into a Water Bubble also fly slower.

Water Bubbles return in New Super Mario Bros. U. Here, they can be found in the Meringue Clouds level A Quick Dip in the Sky. They are the main key to progressing through the vertical level. Other than that, they function identically to how they do in New Super Mario Bros. Wii.
